摘要

硝化纤维微球因其固有的安全性、强流动性和高爆炸力,在推进剂和发射药中得到了广泛的应用。然而,这些微球的传统制备方法往往因工艺复杂、安全系数低和球形度差而受到阻碍。本研究探索了一种利用微流体技术制备硝化纤维微球的创新方法。我们设计并组装了两个高通量制备装置--一个同轴装置和一个离心装置--并采用了三维打印技术。我们的研究结果表明,与传统的单通道微流控技术相比,效率提高了 18 倍。此外,我们还研究了这些装置对微球粒度分布的影响。所提出的装置具有显著的优势,包括降低成本、提高效率和缩短生产周期,这表明它有望在硝酸纤维素微球制备领域得到广泛应用。

Preparation of nitrocellulose microspheres based on low-cost high-throughput microfluidic technology

Nitrocellulose microspheres have garnered extensive use in propellants and launching agents due to their inherent safety, robust flowability, and high explosive power. However, conventional preparation methods for these microspheres are often hampered by complex processes, low safety factor and poor sphericity. This study explores an innovative approach to nitrocellulose microsphere fabrication utilizing microfluidic technology. We designed and assembled two high-throughput preparation devices—a coaxial and a centrifugal device—employing 3D printing technology. Our findings demonstrate an 18-fold increase in efficiency over traditional single-pass microfluidic techniques. Additionally, we examined the impact of these devices on the microspheres’ size distribution. The proposed device showcases significant advantages, including reduced cost, enhanced efficiency, and shorter production cycles, indicating promising potential for wide-scale application in nitrocellulose microsphere preparation.

期刊介绍: Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include: 1.000 Fundamental principles of micro- and nanoscale phenomena like, flow, mass transport and reactions 3.000 Theoretical models and numerical simulation with experimental and/or analytical proof 4.000 Novel measurement & characterization technologies 5.000 Devices (actuators and sensors) 6.000 New unit-operations for dedicated microfluidic platforms 7.000 Lab-on-a-Chip applications 8.000 Microfabrication technologies and materials Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
